TO ALL WHOM IT M AY CONCERN:

Be it known that I, ISAAC'B. IIYMER, of Warsaw, in the county of Kosciusko, State of Indiana, have invented a new and useful Improved Railroad Rail; and I do hereby declare the following to bea full, clear, and exact description of the nature, construction, and operation of the same, suicient to enable one skilled in the art to which it appertains to` construct and use the same, reference being had tothe accompanying drawings, which are made part of this specification, and in which the same letters indicate similar parts.

Figure 1 is a perspective view. i

Figure 2 is a horizontal section on the line a b, fig. 3.

Figure 3 is a transverse section on the line c d, fig. 2.

This consists of a base-piece with foot-flanges and a vertical rib which supports the shank of the T-rail. Side-plates rest against the rib and shank, and are secured by bolts. The sides of the shank and rib, as well as the face of the side-plates, are so grooved as to -reduce the contacting surface to improve the joint.

In the drawings, A is the T-rail, having a shank, a, which rests upon the rib b of the foot-piece B, which has lateral anges, m m. C Cv are side-pieces which rest on each side andsupport the T-rail, the bolts D passing through from side to side, the upper set piercing the side-plates and the shank a, and the lower set piercing the side-plates and the rib b, and secured by nuts and washers. To avoid tting thewhole surface of the side-plates C against the shank a, and rib b, grooves are made in each of the contacting faces, so that they.

bear upon each other at only about one-halt` of their surfaces. Thejoints of the four portions which thus combine to form a railroad rail are broken, so that no two are divided at any one point of transverse section, a seen in figs. 1 and 2. i

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

'lhe arrangement of the T-rail imposed upon the foot-rail, and the two side-plates bolted thereto, the contactng face of the sha-nk a, rib Iz, and side-plates C C, being grooved as described and represented.

To the above specification of my invention I have set my hand this day of ISAAC B. HYMER.
